bokio_get_item

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnlyHint and openWorldHint. The description adds no behavioral context beyond what annotations provide, such as return format, error handling, or response structure. With annotations present, the description should add value but fails to do so.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Extremely concise single sentence. It is front-loaded and contains no fluff. However, it may be slightly too brief given the need for parameter guidance, but the structure is appropriate for a simple get-by-id operation.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given low schema coverage, no output schema, and sibling tools that list items, the description is incomplete. It does not mention that companyId defaults to an environment variable, nor does it describe the returned item object. The simplicity of the tool does not excuse the lack of helpful context.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 50% (companyId has description, itemId does not). The description does not explain itemId format or how to obtain it. It adds no semantic value beyond the schema's minimal documentation.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

The description 'Get an item by id' clearly identifies the action (get) and resource (item) with a specific lookup method (by id). It distinguishes from sibling bokio_list_items, which lists items, making the tool's unique purpose evident.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus alternatives. It does not mention that bokio_list_items should be used for listing all items, nor does it specify prerequisites like needing an itemId from a list call first.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
